An Extreme Bounds Analysis Using Time Series Data

This study finds that reducing speed limits (to 55 mph) in the U.S. results in a reduction of fatality rates. In addition, the proportion of newer vehicles on the highways (subject to newer safety regulations) has a significant effect on fatality rates. The analysis is conducted using extreme bounds analysis applied to a time series model of the determinants of U.S. fatality rates. This model incorporates many policy and socio-economic variables. The determinants of automobile related fatalities have been of great interest among economists, statisticians and government officials lately. Statistical models and techniques of various degrees of sophistication have been employed to evaluate th
